  • Publication number: 20130326953
    Abstract: Provided is a gasification method of a carbon-containing material, the method including: (a) reacting a carbon-containing material to be treated under the presence of a catalyst with steam to produce a syngas containing hydrogen, carbon monoxide and carbon dioxide; (b) generating a carbon dioxide rich gas by introducing a portion of the syngas that has produced in step (a) into a combustion process, and/or separating hydrogen and carbon monoxide from the syngas produced in step (a); and (c) recycling, to step (a), the carbon dioxide rich gas that has been produced in step (b). By the method, the necessity of separating or collecting and storing carbon dioxide for reducing carbon dioxide is eliminated to minimize costs for constructing a special device and facility for the separation or collecting and storage of the carbon dioxide.
